WILLIAM HENRY KNIGHT, or PORTLAND, OREGON.

CAR COUPLING.

SPECIFICATION forming part of Letters Patent No. 331,066, dated November 24, 1885.

Application filed June 15, 1885. Serial No. 168,792. (No model.)

To aZZ whom it may concern.-

Be it known that 1, WILLIAM H. KNIGHT, of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Car-Coupling, of which the following is a full, clear, and exact description.

The invention consists in the combination, with a draw-head, of a cross-bar in the drawhead, a rod projecting upward from the crossbar, a spring acting on the said rod, and 1evers for moving the rod and cross-bar upward, all as will be fully set forth and described hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 shows a draw-head in side View and another in longitudinal sectional elevation. Fig. 2 is an end View of a car provided with my improved cancoupling, parts being broken out. Fig. 3 is a plan view of the coup ling'link. Fi g. 4. is an enlarged cross-sectional View on the line 00 00, Fig. 1.

The draw-head A is held on the bottom of the car B, and through the draw-head the vertical rod G passes, which extends up to the roofof the car, and is guided by an arm, D, on the end of the car. The lower end of the rod 0 is screwed into a cross-bar, E, in the drawhead, which cross-bar is passed through the slots F in the sides. of the draw-head, and

' which bar E is adapted to move up and down with the rod 0. The rod 0' is provided with an annular groove, G, and on the top of the draw-head a spring'bar, H, is secured, which has its free end forked, the prongs of the fork being in the groove G. The said spring-bar H can press down the rod 0 until the spring rests fully upon the top of the draw-head, and when the rod G is lowered as far as possible the cross-bar E is a short distance above the bottom of the draw-head. The rod 0 is also provided with an annular groove, J, in which the prongs of a fork, K, are placed, which fork is formed on the bent end of a lever, K, pivoted on the end of the car and extending to the side. The rod 0 is provided at the up .per end with an annular groove, L, which receives the prongs of a fork, M, on the endof a lever, M, pivoted on the top of a car. The

coupling-link N haseach end provided with a bevel hook-fork, O, the part between the pronged ends having half the height of said prongs, as shown in Fig. 1. The crossbar E can be adjusted higher or lower on the rod 0, as may be necessary.

The operation is as follows: lVhen the link Nis forced into the draw-head, the beveled prongs strike the bar E and force the same upward, and when the ends of the prongs have passed the bar E the spring-H forces the bar E downward and rests against the shoulders at the ends of the prongs, thus preventing withdrawing the link.

To uncouple the cars the bar E on that drawhead must be raised from which the link is to be drawn. This is done by pressing down the levers M or K, and as soon as the levers are released the rod 0 and bar E are pressed down by the spring H. l/Vhen the cars are coupled, the rod 0 is between the prongs of the hookfork 0.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a car-coupling, the combination, with a draw-head, of a cross-bar in the same, a rod screwed in the cross-bar, and a spring secured on the draw-head, and having its free forked end in an annular groove in the rod, substantially as herein shown and described.

2. In a car-coupling, the combination, with a draw-head, of a cross-bar in the same, a rod screwed in the cross-bar and projecting from the top of the draw-head, a spring acting on the rod, and one or more levers pivoted on the car, and having forked ends which are in annular grooves in the rod, substantially as herein shown and described.

3. In a car-coupling, the combination, with a draw-head having slots in the sides, of a cross-bar having its ends passed into said slots, a rod projecting upward from the crossbar, a spring acting on the rod, and one or more levers pivoted on the car, and having their forked ends passed into annular grooves in the rod, substantially as herein shown and described.

WILLIAM HENRY KNIGHT.
